This INIU power bank comes with a substantial 20,000mAh, or 74Whr battery capacity. Considering an 80% power efficiency, here's how many full recharges you can expect for each gaming handheld:

  • Nintendo Switch (16Whr): about 3.7 times
  • Steam Deck (40Whr): about 1.9 times
  • Apple iPhone 16 (14Whr): about 4.2 times
  • Apple iPhone 16 Plus (18Whr): about 3.3 times

The INIU power bank features three output ports: one built-in 45W USB Type-C cable, one 45W USB Type-C port, and one USB Type-A port with up to 18W of power. The 45W Power Delivery is sufficient to charge the Nintendo Switch (18W) and Steam Deck (40W) at their fastest rates. It's also an excellent choice for charging your Apple iPhone 16, as ChargerLAB has demonstrated that the maximum charging rate for even the Pro Max model caps at about 30W.

The built-in cable is a standout feature often found on newer, more expensive power banks, eliminating the need to carry an additional USB Type-C cable. When you're on the move, the USB plug can be clipped onto the power bank to create a convenient lanyard. The cable is robust, with a break strength of 44 pounds, and the lanyard loop when attached to the power bank has a break strength of 13 pounds.
